This study will accrue in two "phases". During the first "phase" of the study, the optimal dose of temsirolimus in combination with cisplatin and cetuximab will be determined. It is expected that between 9-12 patients will be needed for this dose finding phase. Once the optimal dose has been determined, an additional 41 patients will be enrolled in the second "phase" of the study. The primary purpose of second phase of the study is to learn what effects, good and/or bad, temsirolimus in combination with cisplatin and cetuximab has on recurrent or metastatic head and neck cancer.
